Fused Magnesium Oxide

Fused Magnesium Oxide Powder is manufactured from high-purity magnesia raw materials, fused in an electric arc furnace at temperatures exceeding 2800 ℃, followed by crystallization, crushing, and precise classification. It is a new crystalline form achieved through phase transformation, offering unparalleled high-temperature resistance, high dielectric strength, and exceptional thermal conductivity. It is an indispensable core material in high-end electric heating, refractory, and functional applications.

Fused Magnesium Oxide Specifications

Fused Magnesium Oxide Feature

• High Melting Point: Up to approximately 2852°C, making it one of the highest melting-point oxides on Earth.
• Excellent Heat Resistance: Maintains structural stability at extremely high temperatures without softening or decomposing.
• Outstanding Thermal Conductivity: At the same time, it is a good electrical insulator, making this combination of properties highly valuable.
• High Electrical Resistivity: Retains excellent electrical insulation properties even at high temperatures.
• Chemical Inertness: Shows strong resistance to many molten metals and alkaline slags.
• High Mechanical Strength: The crystalline structure formed after melting and recrystallization is dense, with high hardness.

Fused Magnesium Oxide Applications

• Heating Elements: The ideal filling material for various metal-sheathed and quartz heating elements, widely used in household appliances (e.g., ovens, water heaters, space heaters) and industrial heating equipment.
• Refractories: A key component in advanced refractory castables, ceramics, and kiln furniture for high-temperature furnaces in steel, cement, and glass industries.
• Functional Filler: Used in high-temperature coatings, plastics, and rubber to enhance the thermal conductivity, insulation, or flame-retardant properties of the base material.
• Electronics & Electrical: Serves as high-temperature insulating substrates and thermocouple insulation materials.

Fused Magnesium Oxide Packaging

The Fused Magnesium Oxide is securely packed in wooden crates or cartons, reinforced with cushioning materials to prevent movement during transit. This packaging approach ensures that the products remain intact and protected throughout the shipping process.
